Read about Extensibility here

I tried this way

      Encounter enc = new Encounter();
	  ClassHistoryComponent cls=new ClassHistoryComponent();
      cls.setIdBase("12345672399863");
	  enc.addClassHistory(cls);
      Extension ext=new Extension();
      ext.getNamedProperty("distcriptions  ");
  	  enc.addExtension(ext);

Response JSON:-

{
  "resourceType": "Encounter",
  "classHistory": [
              {  "id": "12345672399863"  }
             ]
 }

not able to get response from HL7 .

I’m not sure what ext.getNamedProperty("distcriptions "); is intended to do. You haven’t specified a url or a value for your extension, so there’s not actually any content to serialize
